In a very large geographically dispersed network (over 50,000 users), access servers might be located in different parts of a city, in different cities, or on different continents. If network latency is not an issue, a central ACS might work; but, connection reliability over long distances might cause problems. In this case, local ACSs may be preferable to a central ACS.

If the need for a globally coherent user database is most important, database replication or synchronization from a central ACS may be necessary. For information on database replication considerations, see Database Replication Considerations, page 2-13and Database Synchronization Considerations, page 2-14. Authentication by using external databases, such as a Windows user database or the Lightweight Directory Access Protocol (LDAP), can further complicate the deployment of distributed, localized ACSs.
